Question

Aballoon is filled with 3.60 L of H2 gas at STP. If the balloon is
taken into a sea where the pressure is 2.50 atm and the temperature is 10.00 °C, what is the new volume of H2 gas in liters?

Answer 1

Answer:

the new volume is 1.49 L

Explanation:

stp is 0 degrees C and 1 atm.

you need to use the combined gas law formula and solve for v2

i converted the C to Kelvin

v2=p1(v1)(t2)/p2(t1)

v2=1atm(3.6L)(283.15K)/2.5atm(273.15K)

v2=1.49

Answer 2

Answer:

1.49
